With only one tuner, your chances of having a problem are fairly low.
In my experience, the most vulnerable times were when multiple tuners
and jobs were starting or stoping at the same time.
No one has responded with problems so perhaps things have gotten
better and I should give it another try. Thanks to all who responded.

I have been running exclusively SMP kernels since the non-SMP/SMP
kernel merge back in 2.6.16 (or was it 2.6.18). Anyway, I had a few
issues with SMP back when I working on 2.6.9, but since 2.6.18
everything has worked well, except for a couple of regressions in the
XFS filesystem somewhere in the early 2.6.20's I believe. I switched
to JFS, but I've heard XFS is working well these days also.<br>
<br>
I run many tuners. Since switching to SMP kernels exclusively I have
run (2) Air2PC ATSC cards with (3) PVR-250, until I swapped them out
for (2) HDHomeRun with (2) PVR-500. I have just started reconfiguring
my backend again keeping the (2) HDHomerun and using HD-PVR instead of
the PVR-500's. All of this was on the primary backend. I have also
run with Fusion HDTV PCI and USB adapters, pchdtv HD2000 and HD3000,
PVR-150, and PVR-USB2 and probably others that I am forgetting.
Needless to say I hammer on it pretty good.<br>
<br>
This is all currently running trunk 21049. I tend to update trunk
every couple of weeks unless I see something really interesting and I
update sooner.<br>
